Hook up two monitors to imac - How to Hook Up One Computer to Two Monitors | Techwalla.com

Do the monitors support DVI? I'm using two DVI screens connected to one of those, using Displayport to DVI adapters. I think I had to use an active adapter for one of them. Not sure if VGA is making a difference. The laptop had to have Optimus enabled, but I'm pretty sure that was so I could enable all three, including the laptop's LCD.

If you own a Windows laptop, this is all very easy to set up. The first step is to determine which type of cable you need. Most modern laptops will have HDMI, DisplayPort, mini-DisplayPort or USB Type-C. If your machine is a few years old, however, you might have only DVI or VGA. The same goes for your monitor. If the inputs and outputs on the monitor and laptop match, happy days: you can purchase a cable for a few quid – such as this simple HDMI lead on Amazon – and hook the two together.
